Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for drying combustible materials to reduce moisture content are slow and complex, requiring additional steps for coating and drying, which complicates the process and does not efficiently accelerate the drying speed.
Innovation Solution
A method involving mixing combustible material particles with a dehydrating liquid emulsion containing synthetic resin to form a mixture, where the particles are coated and then dried, accelerating moisture evaporation and simplifying the process by forming a synthetic resin coating that reduces moisture content to 20 mass % or less.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional hot-air drying or vacuum drying is used to reduce moisture content, then the combustible material can be dried, but the drying speed is slow
Solution Approach 1:
The patent introduces a dehydrating liquid as an intermediary substance that facilitates rapid moisture removal. The liquid penetrates the combustible material particles, absorbs moisture through osmosis and capillary action, and enables fast drying without requiring prolonged exposure to heat or vacuum conditions.
2Reliability
If a coating layer is formed on dried combustible material to reduce moisture absorption, then storage stability improves, but the process becomes complicated with additional steps
Solution Approach 1:
The patent combines the drying function and coating protection function into a single integrated step. The dehydrating liquid serves dual purposes: it rapidly removes moisture from the combustible material and simultaneously forms a protective coating layer on the particle surfaces that prevents moisture reabsorption during storage, eliminating the need for separate coating operations.
Solution Approach 2:
The dehydrating liquid performs multiple functions simultaneously: it acts as a drying agent that penetrates and removes moisture from particles, serves as a coating material that forms protective films on surfaces, and provides storage stability by preventing moisture reabsorption. This multi-functionality simplifies the overall process while achieving multiple objectives.

AI summary
A method for manufacturing dried combustible material includes: a mixing step of mixing a number of particles made of combustible material containing moisture and a dehydrating liquid made of an emulsion containing synthetic resin to form a mixture in which surfaces of the particles are made contact with the dehydrating liquid; and a drying step of forming a synthetic resin coating made of the dehydrating liquid dried on the surfaces of the particles and evaporating the moisture of the particles, to form coated particles including the particles having a reduced moisture content percentage and the synthetic resin coating that covers the surfaces of the particles, and produce dried combustible material made up of the coated particles.
